Lowest-carb protein powder per 25 g of protein

Total carbohydrate on a protein powder label is reported per serving, and serving sizes are not standardized across brands. This page ranks protein powders by total carbohydrate grams per 25 grams of protein, putting every product on the same protein-adjusted basis so a small, carb-light serving and a large, carb-heavier serving can be compared fairly. Lower carbohydrate content is not automatically healthier or more effective — some carbohydrate comes from added sugar, some from thickeners or flavoring systems, and some from the protein source itself, such as certain plant proteins. If carbohydrate content matters for your eating pattern, also check the sugar and fiber figures on each product page, since two products with the same total carbohydrate can differ in how that carbohydrate is composed. Nutrition figures reflect the most recent reviewed label, not a live feed.
